OBSERVING SAFETY PRECAUTIONS
Follow the appropriate warnings and cautions when performing the tasks specified in thismanual. You must connect the specified cables and wires only in the order listed and asindicated in the installation instructions. Additionally, read and understand all installationprocedures before beginning.
OBSERVING ESD PRECAUTIONS
Observe these electrostatic discharge (ESD) precautions when installing the AV8000 system.Follow installation procedures in the order that they are given.
• Follow local grounding practice to ensure a good frame ground connectionto the AV8000 chassis. The frame ground is required for secondary voltageprotection.
• Electrical and mechanical shock hazards are present throughout thesystem; be aware of this possibility when power is applied to the chassis.Only qualified personnel should service the system.
• Do not connect the AV8000 chassis battery wires to a live power source.Ensure that you remove fuses from the CO equipment bay for each circuityou will use.
• The equipment must be connected to a protective ground in accordancewith the instructions provided in this manual. Improper grounding mayresult in an electrical shock.
• The minimum bend radius for a fiber-optic cable is 1.5 inches (38.10 mm).Do not use a bend radius of less than 1.5 inches when looping thefiber-optic cable in the cable tray.
• Do not look directly at the fiber-optic ports on the front of the OC3 networkcard or into the end of any fiber-optic cable.
This symbol placed next to a paragraph title or within a paragraph indicatesthat the entire procedure involves equipment sensitive to electrostaticdischarge. You must wear an antistatic wrist strap connected to the ESD jackon the AV8000 chassis to perform the installation procedures. You must alsoobserve normal ESD precautions when handling electronic equipment. Do nothold electronic plugs by their edge. Do not touch components or circuitry.

AV8000 Installation Manual 3
PLANNING THE AVIDIA SYSTEM
Use the following sections to select components for the Avidia system. Allow for futureexpansion when you select and place components.
Compatibility
Select components for your system that are compatible:
• network card(s) to meet the network interface requirement, as well as the bandwidth andtraffic needs of your network (see “Adding to an Existing System” on page 5 for other usesof network cards)
• subscriber cards to meet the network, transmission, and distance needs for your subscribers,for example:
– Does symmetric (frame SDSL, IDSL) or asymmetric (ADSL) transmission best meetthe applications needs for the subscriber?
– Which transmission type provides service to a subscriber who is distant from the CO?
– Which transmission type provides the appropriate rate for the reach?
• for POTS, use ADSL subscriber cards AV541 (without line protection) and connect to aVOICE shelf to multiplex voice and data
• Customer Premises Equipment (CPE) must be compatible with transmission type of thesubscriber card, for example:
– for ADSL subscriber cards, use Megabit Modem 700F, 600F, 500L, 400F or otherDMT ADSL modems
– for frame SDSL subscriber cards, use Megabit Modem 300S or other SDSL modems
– for IDSL subscriber cards, use modems recommended as a result of compatibilitytesting and listed on the ADC.com Web site
– for cell SDSL subscriber cards, use modems recommended as a result of compatibilitytesting and listed on the ADC.com Web site
If selecting an ADSL subscriber card, use the Avidia Model AV541-LP (with lineprotection) to connect directly to an MDF. Use the Avidia Model AV541 toconnect to a voice shelf.
Planning the Avidia System
4 AV8000 Installation Manual
Card Placement
You may want to strategically leave slots available for expansion (see “Adding to an ExistingSystem” on page 5). Install cards in these AV8000 chassis slots:
• management card in slot 1
• OC3, DS3, and DSX-1 network cards in slots 11 and 12 (OC3 card can be used in asubscriber slot for special applications such as subtending, see Chapter 8); typically, useslot 12 as the primary network card slot
• 8xDS1and 8xE1 network card in any subscriber card slot (S2 through S10 andS13 through S21)
• ADSL, cell SDSL, frame SDSL, and IDSL subscriber cards in any subscriber card slotS2 through S10 and S13 through S21, in any combination (it is efficient to place ADSLcards in adjacent slots for cabling purposes when you connect to a Voice shelf to combinevoice and data)
• Empty card slots should be filled with one or more of the blank faceplates provided withthe AV8000. This not only reduces the levels of electromagnetic radiation emanating fromthe chassis, but also aids in maintaining optimum cooling for the cards installed in thesystem.
Chapter 1: Prepare for Installation
AV8000 Installation Manual 5
Adding to an Existing System
When selecting system components, consider future expansion to your Avidia system, withthese as possible options:
If you want to add a: Then:
AV8000 Chassis Consider installing the first chassis in the top position in a 7-foot Telco rack to allow further expansion in the middle and bottom positions. Remember, you can have a maximum of three AV8000 chassis per rack, when a fuse panel is not installed in the same rack.
Network card for:
Redundancy Add a second network card, of the same type, in slot 11 to have a backup connection to the same network uplink source.
Second network connection Add a second network card, of the same or of a different type, in slot 11 to connect to a separate or second network uplink source.
Subtending Add a one or more additional network cards to subtend other Avidia chassis that are downstream from the subtending chassis. This card can be:• another DS3 card in slot 11• another OC3 card in slot 11 or any subscriber slot (2-10 or 13-21)
• 8xDS1 card in any subscriber slot (2-10 or 13-21)
• 8xE1 card in any subscriber slot (2-10 or 13-21)
Subscriber card Leave subscriber slots (2-10 or 13-21) open to accommodate expansion of subscriber services. You may want to group cards in the chassis for ease of cabling. There is no technology limitation, however, for card placement. Available xDSL cards are:• 12-port ADSL (two 12-port ADSL cards are available (AV541 and
AV541-LP). Use the AV541-LP card when connecting the ADSL subscriber line directly to the MDF for data transmission that does not include POTS. Use the AV541-LP card when you connect the subscriber line to a voice shelf to multiplex data with POTS. The voice shelf provides the line protection required for the ADSL card.
• 24-port cell SDSL
• 24-port frame SDSL• 24-port IDSL
POTS with ADSL Leave space in the CO rack for co-locating a voice shelf. Also, when you combine a voice shelf with an AV8000 chassis for implementing data and POTS, select the ADSL card without line protection. The voice shelf provides line protection for the ADSL card.
Installation Site Requirements
6 AV8000 Installation Manual
INSTALLATION SITE REQUIREMENTS
Chassis Installation Requirements
The AV8000 mounts in a 23-inch, 7-foot or 71/2-foot CO Telco rack. You can install up to threechassis in one rack. Allow adequate space for ventilation and cabling. The table below showschassis dimensions and minimum clearances for installation.
Power Requirements
Verify that the power source where you will connect the Avidia system is properly groundedand falls within the recommended voltage range of -42.5 Vdc to -56.5 Vdc, with a minimum of30 Amps.
Each AV8000 system provides a terminal block with connection points for two -48 Vdc Telcosupplied battery sources. Only one battery connection is required, with the second connectionprovided for redundancy. The system also requires an external fuse panel with separate fusingfor each battery source used.
Alarm Requirements
The AV8000 system monitors alarm conditions, including alarms occurring at the remote end.Connect alarm pins, when required by local practice, to indicate the alarm conditions such asaudible alarms, visual alarms, or power relay alarms. You can connect an Alarm Cut Off (ACO)pushbutton to disable audible alarm output remotely.

AV8000 Installation Manual 7
Clocking Requirements
Avidia system clocking provides the capability to synchronize all data transmissions with acommon timing source within the Avidia System. Redundancy is provided, through the priorityranking of clock sources, in order to achieve fault tolerance and timing recovery in the case ofa clock source failure. User configuration provides for selection and ranking of clock sources.A clock source is selected for individual cards in a system. At this time, only the followingsubscriber cards support the system clock (Sysref Clock) feature:
• AMC
• DS3
• OC3
• DSI/E1
• IDSL
Clocking Systems
There are four related clocking systems associated with an Avidia chassis. These are discussedin the following sections.
BITS OUT Clock
The first clocking system for the Avidia chassis is the BITS clock. A clock source is selectedthat will serve as the BITS OUT clock. Potential BITS OUT clock sources are BITS IN 1, BITSIN 2, or none. The BITS OUT clock source is selected by the user, through configurationsoftware, and routed by the primary network card to the BITS OUT wire wrap pins on the backof the Avidia chassis.
Network Card Clock/System Reference Clock
The second clocking system is the System Reference clock (Sysref). Cards in the network cardslots, slots 11 and 12, are user configured to select the Sysref clock source. Both network cardslots can drive Sysref clock, but not at the same time. Normally, one network card (primary)provides Sysref to the Avidia backplane and the other network card (secondary) uses the Sysrefclock off the backplane. The Sysref clock signal is also made available to all of the subscribercards from the backplane as well. Sysref clock sources are BITS IN 1, BITS IN 2, a networkcard’s ports’ recovered receive clock, or the network card’s local oscillator. Sysref clock ismonitored by the network card for failure.
Installation Site Requirements
8 AV8000 Installation Manual
Subscriber Card Clock
The third clocking system provides clocking for the subscriber card. Subscriber card clocksources are Sysref, subscriber card’s ports’ recovered receive clock, or subscriber card localoscillator.
Port Clock
The fourth clocking system provides clocking for the subscriber card port. This clock is protocoldependent. Potential port clock sources are:
• Local (uses the card clock source that was selected for the subscriber card)
• Loop (clock received at the port is recovered and used to transmit data).
If you do not configure a clock source for a card, configuration defaults to the card’s localoscillator.
Typical Clock Source Configuration
Typically, the primary network card receives the master clock from a BITS clock such as aStratum 1 clock, through the chassis backplane inputs BITS IN 1 or BITS IN 2. The primarynetwork card outputs the clock signal BITS OUT, to the backplane wire wrap pins, and Sysrefto the Sysref backplane bus. The BITS OUT clock daisy chains the master clock (BITS out toBITS in) through network cards from one Avidia shelf to the next in a central office rack. TheSysref clock is distributed on the Backplane of the Avidia shelf for use by the subscriber cardsand the secondary network card not currently configured to supply this clock signal.
On the subscriber cards, the Sysref clock can be used to synchronize data transmissions. Or, theuser can configure the subscriber card to utilize the recovered received clock from a port fortransmitting data.
Clock Priority and Redundancy
Clock sources for the network cards and the subscriber cards are configured and ranked by theuser. Ranking allows you to indicate the priorities for each clocking source, throughconfiguration software, so that if the present clocking source should fail, the next lower rankedclock source would take its place providing redundancy for the failed clocking source.
Clock sources are constantly monitored by Avidia software; therefore, when a failed clockbecomes available once again, the system automatically switches to this recovered higherranking clock source.
Chapter 1: Prepare for Installation
AV8000 Installation Manual 9
Clocking the IDSL Card
The IDSL subscriber card requires special clocking consideration. Normally, the BITS IN clockis used for locally clocking the IDSL frame-based card. In this case, the BITS clock must be:
• T1 signal, either framed or unframed
• DSX-1 signal, either framed or unframed
• minimum of one clock pulse per 8 bits time frame
• Alarm Indicator Signal (AIS) acceptable
• only bipolar violation accepted is B8ZS

OC3
An OC3 network card has dual-PHY (two physical) connectors on the card front, behind thesafety cover. One interface provides the primary network uplink connection. The secondinterface provides Automatic Protection Switching (APS), which is a redundant connection.When implementing APS, provide cables and connectors for two physical ports. If notimplementing APS, provide a cable and connector for only one physical port. Select the fiberand connector as follows, from the table below:
• For an AV311 OC3 network card, use multimode fiber with SC fiber connectors.
• For an AV312 OC3 intermediate-range (IR) network card, use single mode fiber withSC fiber connectors.
• For an AV313 OC3 long-range (LR) network card, use single mode fiber with SC fiberconnectors.
The minimum bend radius for the fiber-optic cable is 1.5 inches (38.10 mm).The diameter of the core/cladding is 62.5/125.5 µm (micrometers).

DS3 INTERFACE CABLES
The DS3 network card provides an interface between the AV8000 system and an ATMbackbone network. The interface to a DS3 network card in slot 11 or 12 is made to a pair ofBNC connectors on the AV8000 backplane (page 32). Use the BNC connector pair as follows:
• DS3-1 for the network card in slot 12
• DS3-2 for the network card in slot 11
For each BNC connector pair, the connectors are labeled:
• TX BNC for the transmit signal from the Avidia network card to the network
• RX BNC for the receive signal from the network to the Avidia network card
When you use two DS3 cards in an AV8000 system, connect the cables (steps on page 35) forone of the following modes (shown in the figure below):
• single physical link mode (one network connection)
• dual physical link mode (two network connections)
• subtending (one network upstream connection, one network downstream connection)
Either DS3 network card can be configured to connect to either set of DS3 BNCconnectors on the AV8000 back plane. During initialization however, thesoftware assigns the DS3-1 connector to slot 12 and the DS3-2 connector toslot 11.
Recommendation: Use a 75 Ω coaxial cable with 75 Ω BNC connectors anda maximum length of 450 feet (137.16 m). Ground the cable shield at one endonly.

Install Network Cards
Network cards provide an uplink interface to an ATM network. They supply both ATM trafficmanagement and physical layer functionality. Only one network card is required to provide alink between the subscriber and the ATM backbone, but you can install a second network cardfor redundancy or for dual homing. See “” on page 76 for more information about redundancyand dual homing configurations. Network cards are typically placed in network card slots 11and 12; however, 8xDS1 and 8xE1 cards must be placed in subscriber card slots 2-10 or 13-21.
Network cards can also provide a subscriber-side connection when used for subtending.Subscriber-side means that the cards do not provide an uplink network connection, but providea connection downstream to another Avidia chassis that is being subtended. See “SubtendingMultiple Systems” on page 86 for more information about how to select and place networkcards for this application. For this type of application, the OC3 card can be placed in subscribercard slots 2-10 or 13-21

Install Subscriber Cards
Avidia subscriber cards provide two-way data communication with the subscribers.Subscriber cards are currently available in several transmission technologies: ADSL,cell SDSL, frame SDSL, and IDSL. You must select subscriber cards for the AV8000 that arecompatible with the subscriber-end equipment:
• Select cell DMT ADSL subscriber cards to connect to cell-based DMT ADSL modems.
• Select frame SDSL subscriber cards to connect to frame SDSL modems.
Cell subscriber cards operate with a data stream of fixed length. The advantage of this format isthat the network does not have to handle different sizes of packets or frames. This broadbandtechnology transmits data quickly and efficiently. There are three cell subscriber cards: AV541,AV541-LP, and AV522.
Frame-based cards operate with a data stream of variable length. By using only a few bytes ofoverhead, the frame format makes efficient use of each frame. This means that more of theframe bandwidth is used for sending user data and less for overhead. Two Avidia cards areavailable for frame-based data: AV421 and AV412.
The table below lists all the subscriber cards available for the AV8000 system.
You can install up to 18 xDSL subscriber cards, 8xDS1 network card(s), and 8xE1 networkcards in chassis slots S2 through S10 and S13 through S21. Install the subscriber cards (page 55)into the chassis:

REDUNDANCY
Redundancy is a feature of the Avidia system. Redundancy includes:
• dual homing, which provides redundancy at a VPC or VCC level (dual homing alsoprovides static load sharing) as described on page 78.
• card redundancy, where a primary network card can switch to a secondary network card ifthe primary card were to fail as described on page 79.
• automatic protection switching (APS) for the OC3 network card with dual-PHYconnectors, where the primary physical port switches to the secondary physical port if theprimary port were to fail as described on page 80.
• DS3 dual port redundancy, which provides both single and dual physical link portredundancy, as described on page 81
Redundancy
78 AV8000 Installation Manual
Dual Homing
Through dual homing, a second network interface (DS3 or OC3 network card) is used in theAvidia system and provides support that includes:
• backup or redundant PVCs with the same destination.
• static load sharing where traffic is directed separately to a primary and to a secondarynetwork card, increasing the amount of traffic that you can send through the system(see page 79).
See the Avidia System Configuration and Management User Manual for information aboutapplying Quality of Service (QoS) to traffic that is assigned to dual homing configurations.
When setting up a system for dual homing, one network card is a primary network card and thesecond network card is a secondary or backup network card. In an AV8000 system, you caninstall the network cards into slot 11 and slot 12. The two network card slots are essentiallysymmetric. At any point, only one of the two network cards will provide cell-bus clocking.Configure ATM VPCs and VCCs to the network card that you choose as primary and configurethe backup VPCs and VCCs to the second network card.
In an Avidia 3000 system, you can install the network cards into slot 2 and slot 3. The networkcard in slot 2 provides cell-bus clocking and must be in the slot when an Avidia 3000 systemis initialized (booted). When there is a failure of the network card in slot two, cell-bus clockingswitches to slot 1. Configure ATM PVPCs and PVCCs to the network card that you choose asprimary and configure the backup PVPCs and PVCCs to the second network card.
Redundancy is another feature of Avidia systems that uses two network cards. Redundancyprovides backup at a card level where dual homing provides backup at a PVC level (PVPCs andPVCCs). See page 79 for more information about redundancy. You can implement bothredundancy and dual homing concurrently in an Avidia system. You must, however, carefullyplan traffic management and QoS to efficiently run the network. See the Avidia SystemConfiguration and Management User Manual for information about traffic management.
Backup ATM Connections
ATM service requires the configuration of ATM connections which comprise PVPCs andPVCCs. PVPCs and PVCCs are the logical connections over which ATM cells are transmitted;these are referred to as the primary PVPCs and PVCCs. You can create backup PVPCs andPVCCs to which the system can automatically switch in the event that primary PVPCs orPVCCs fail. These are referred to as secondary PVPCs and PVCCs. The secondary PVPCs andPVCCs are configured to the second (redundant) network card in the Avidia system.
Chapter 8: System Configuration for Special Applications
AV8000 Installation Manual 79
Static Load Sharing
The dual homing feature of static load sharing allows you to increase the amount of traffic thatyou can send through the system by allowing you to direct traffic to two separate network cards.The uplink for both network cards (DS3 and OC3) is from the same ATM source, but theinformation that is transmitted may be directed either to the same or to different destinationdevices. The network cards can be of the same type (both OC3, for example) or they can be ofdifferent types (an OC3 and a DS3, for example).
Through StarGazer or the Avidia command-line or Web interfaces, you can direct some Avidiasystem ATM cross-connections to one of the network cards and then direct other ATMcross-connections to the second network card. If you also implement card-level redundancy andbackup or secondary PVCCs and PVPCs, you need to carefully balance loads and managetraffic and QoS to efficiently use the network and the bandwidth available for each networkcard.
If one network card fails, the second network card takes over the functionality of the failednetwork card, and re-establishes all the connections. This can result in too heavy a traffic loadon the second network card. To handle this, you can configure the recovery priority by traffictype (for example, CBR first, rt-VBR second).
Network Card Redundancy
The Avidia system network cards provide two types of ATM connection redundancy:
• connection redundancy between the network card and the destination ATM end system
• network card redundancy, should a network card fail
Connection Redundancy—Network Card to ATM End System
When a connection goes down between the network card and the destination ATM end system,the network card detects the failure and attempts to re-establish the connection by automaticallyretrying or re-routing it, using signaling. This requires that the network card and the destinationATM end system both support signaling.
To enable connection redundancy between the network card and the destination ATM endsystem, you configure an end-to-end connection using SPVCs.
SPVCs comprise:
• a cross-connect (PVCC or PVPC) from a cell-based subscriber card to a network card
• an SPVC from the Avidia network card across the ATM network to an ATM end system
Redundancy
80 AV8000 Installation Manual
Network Card Redundancy
If a network card fails, and you have a second network card installed, the second network carddetects the failure, takes over all of the functionality of the failed network card, andre-establishes all of the connections. This requires two ATM network cards to be installed in theAvidia system, and at least two uplinks from the Avidia system to the ATM network.
Network card redundancy requires configuring static routes in the ATM Routing Table. Whena network card fails, the system uses the ATM Routing Table information to re-route SPVCs toa specified slot and port on the secondary network card, based on the destination ATM address.See the Avidia System Configuration and Management User Manual for information aboutconfiguring static routes.
Managing Traffic for Redundancy
You can configure the Avidia system for static load sharing, using two installed network cards.However, if one network card fails, the second network card takes over the functionality of thefailed network card, and re-establishes all the connections. This can result in too heavy a trafficload on the second network card. To handle this, you can configure the recovery priority bytraffic type (for example, CBR first, rt-VBR second). If you do not configure recovery priorities,the connections are recovered sequentially until no further resources are available. After thatpoint, the remaining connections are dropped. See “Static Load Sharing” on page 79 for moreinformation about static load sharing and traffic management.
When an initial call request is unsuccessful, or an existing connection fails, and the call has beenretried the maximum configured number of times, the call request is re-routed using the othernetwork card.

OC3 network cards have two physical SONET interfaces, each with a transmit and receive port.Under normal operation, all traffic is carried through the first interface; the second is not used.Automatic Protection Switching (APS) uses the second interface to provide a backup to the first.
Avidia uses 1+1 unidirectional APS. In this version of APS, the primary interface is defined asthe working channel. The second interface is defined as the protection channel. Transmitted datais sent over both channels. Data is normally received through the working channel. However, ifthe working channel fails, received data automatically switches to the protection channel.
By default, APS is disabled on Avidia systems. You must enable APS for automatic switchingto occur. See the Avidia System Configuration and Management User Manual to enable andconfigure APS.

DS3 Dual Port Redundancy
When you use two DS3 cards in an AV8000 system, connect the cables as described in thesection “DS3 Interface Cables” on page 33 for one of the following modes:
• single physical link mode (see figure on page 84)
• dual physical link mode (dual homing) (see figure on page 82)
Dual Physical Link Network Card Redundancy
If a network card fails, and you have a second network card installed, the second network carddetects the failure, takes over all of the functionality of the failed network card, andre-establishes all of the connections. This requires two ATM network cards to be installed in theAvidia system, and at least two uplinks from the Avidia system to the ATM network.Thisredundancy method is known as Dual Physical Link Port redundancy and is the defaultredundancy mode.
Network card redundancy requires configuring static routes in the ATM Routing Table. Whena network card fails, the system uses the ATM Routing Table information to re-route SPVCs toa specified slot and port on the secondary network card, based on the destination ATM address.
Implementing DS3 Port Redundancy
StarGazer allows network port redundancy to be implemented in either a Dual Physical Linkmode or a Single Physical Link mode.
Dual Physical Link Mode. In the Dual Physical Link mode, a DS3 card positioned in slot 11of the AV8000 default to port 2 as the primary active link and a DS3 card placed in slot 12 ofthe AV8000 defaults to port 1 as the primary active link. This default configuration allows bothcards to be activated simultaneously and carry network traffic over separate physical networkslinks. In this mode, however, different active port numbers must be used for each DS3 networkcard and both port 1 and port 2, on either card, must not be activated simultaneously.
If both DS3 cards and network links are active, then redundancy is provided by switching xDSLtraffic from the failed DS3 card or network link, to the remaining active DS3 card and itsassociated network link. If only one DS3 card and link is active and the other DS3 card andnetwork link are idle, reserved for backup, then redundancy is provided by activating the idleDS3 card and link and switching xDSL traffic from the failed DS3 card to the now active backupDS3 card and its associated network link. In Dual Physical Link mode, the two network cardsare not required to be of the same media type—a DS3 card may be mixed with an OC3 card withno reduction in functionality.
Redundancy
82 AV8000 Installation Manual
Dual Physical Link mode is the default port redundancy configuration, and is automaticallyselected if Single Physical Link mode redundancy is turned-off during configuration of the DS3cards. Redundancy of either type is a chassis-wide system configuration parameter involving allof the installed network cards in a chassis.
Single Physical Link Mode. In the Single Physical Link mode, port redundancy requirestwo DS3 cards—a DS3 card may not be mixed with an OC3 card, nor can two OC3 cards beutilized in place of DS3 cards. However, if mixed OC3/DS3 cards must be used, then portredundancy may only be configured for Dual Physical Link mode. As in earlier versions, use ofa single DS3 network card is allowed, although no port redundancy is possible under thisconfiguration.
Whereas the Dual Physical Link mode automatically activates port 2 for slot 11 and port 1 forslot 12, by default, Single Physical Link mode selects the active port and slot through an internalalgorithm, that is in part, based on the user designation of either port 1 or port 2 as theredundancy port during configuration.
The DS3 network card is configured for Single Physical Link mode redundancy through theWeb, command line or StarGazer interface. If Single Physical Link mode is turned-off, thenDual Physical Link mode is assumed. Configuration procedures for setting up port redundancycan be found in the DS3 Configuration sections of the Avidia software manuals.
The remainder of this section will describe the operation of dual port redundancy under both theDual Physical Link mode and the Single Physical Link mode configurations. The networkconfiguration will be examined both before and after a failure-induced automatic switch-overof network traffic. If you decide to employ port redundancy in your system, you must paycareful attention to your configuration and cabling.
DS3 Card Switch-Over—Dual Physical Link Mode
In Dual Physical Link mode, failure of one of the DS3 network cards (primary), or its associatednetwork link, will cause all xDSL traffic through that interface to be automatically switched tothe remaining DS3 network card (secondary) and routed over the alternate physical networklink. If the secondary physical network link is currently active, the traffic diverted from thefailed primary network card will be combined with the original traffic through the secondarynetwork card and its overall traffic load will be increased. This load increase is an importantconsideration when selecting this port redundancy mode.
The following figure shows the before and after configuration of the network interfacefollowing a failure in the DS3 card in slot 12 (primary) or a failure in the network link associatedwith this card, where both the primary and secondary physical network links are active. Initially,traffic is flowing through port 1 of the DS3 card in slot 12 (primary) to network link 1 andthrough port 2 of the DS3 card in slot 11 (secondary) to network link 2. This is the initial defaultconfiguration when operating in Dual Physical Link mode.
Chapter 8: System Configuration for Special Applications
AV8000 Installation Manual 83
After switch-over has occurred, all ADSL traffic is diverted from the DS3 network card in slot12, port 1 to the DS3 network card in slot 11, port 2. Traffic originally directed through networklink 1, is now be diverted and added to the network traffic through link 2.
As mentioned earlier, although the secondary physical network link may be active, it may alsobe maintained in standby mode and reserved strictly for backup purposes. In this case there willbe no increase in traffic load to the network after switch-over.

Although two DS3 network cards are shown in the preceding figure, Dual Physical Link modeallows a configuration based on an OC3/DS3 network card combination. This is not the casewith Single Physical Link mode.
DS3 Card Switch-Over—Single Physical Link Mode
In Single Physical Link mode, failure of one of the DS3 network cards (primary) will cause allxDSL traffic through that interface to be automatically switched to the backup DS3 networkcard (secondary) and routed over the same physical network link. Since traffic diverted fromthe failed primary network card will continue to be directed through the same physical networklink, any failure at the network level can not be corrected by using the Single Physical Linkmode—only DS3 card-level failures can be addressed and corrected by this method.
The figure below shows the before and after configuration of the network interface following afailure in the DS3 card in slot 12 (primary). Initially, traffic is flowing through port 1 of the DS3card in slot 12 to network link 1 and there is no traffic through port 2 of the DS3 card in slot 11(secondary). Notice that in this case, the DS3 card in slot 11 is idle and that network link 2connected to port 2 is not active. This is the normal dual network card configuration whenoperating in Single Physical Link mode with port 1 selected for port redundancy. The softwareport selection algorithm will reverse this active/idle card configuration if port 2 instead of port1 is designated as the redundancy port.
Chapter 8: System Configuration for Special Applications
AV8000 Installation Manual 85
After switch-over has occurred, all ADSL traffic is diverted from the DS3 network card in slot12, port 1, to the DS3 network card in slot 11, port 1. Traffic originally directed through networklink 1 is still directed through this same network link and there is no increase in network trafficload.
Two DS3 network cards are shown in the figure above—this is the only configuration possible.Single Physical Link mode requires that two DS3 cards be used in the network interfaceconfiguration and does not permit an OC3/DS3 network card combination. If an OC3/DS3network card combination is required, then the network interface must be configured as a DualPhysical Link.

Subtending Multiple Systems
86 AV8000 Installation Manual
SUBTENDING MULTIPLE SYSTEMS
Multiple systems can be implemented, viewed, and managed as if they were one system.This type of management is known as subtending. To subtend, connect and configure Avidiasystems in one of two ways: a star configuration or a daisy chain configuration.
In either implementation, multiple systems connect to one system that aggregates thetransmission of all the attached systems and provides one network uplink. The aggregatingsystem is known as the subtending or source system and each of the systems connected to it areknown as the subtended or destination systems.
See the figure below for a representation of both daisy chained and star configured systems. Inthe figure, the subtending systems in each configuration aggregate the transmissions of thesubtended systems and provide a network uplink via OC3 to the ATM Switch.

In the deployment of xDSL services, subtending helps the service provider satisfy thecustomer’s demand for bandwidth against the WAN trunk capacities. Subtending helpsto expand the availability of service more cost effectively and expand to the more remotesubscribers. Subtending services, offered by Avidia, are complemented by its ATM features andprovide benefits such as:
• optimizing the use of the more expensive WAN transmissions, such as DS1, DS3, and OC3,by using only as much of the bandwidth as required
• incrementally adding bandwidth without changing the hardware (for example, 8xDS1 and8xDSX-1 cards have eight separately configurable DS1 ports)
• using an Avidia system at the edge of the network (aggregates and provides uplink) ratherthan using a third party switch
• concentrating data efficiently
• organizing the network through the use of VPCs and VCCs
• selecting ATM QoS classes to effectively groom traffic within the network
Set up subtending using AV8000, AV3000 and AV2200 systems. AV8000 and AV3000systems can both subtend and be subtended while the AV2200 is typically a subtended systemand does not subtend other systems. Then, within these Avidia systems, use the cards listed inthe following table to set up the appropriate subtending or subtended interfaces. To subtend,connect a subscriber-side interface of the subtending system to the network-side interface of thesubtended system. A network-side interface must be in slot 11 or 12 of an AV8000, in slot 2 or3 of an AV3000 or in slot 1 of an AV2200 to provide a cell bus clock and cell bus arbiter clockfor the Avidia system. The network-side interface also provides either the network uplinkinterface to the subtending system or the network interface from the subtended to the subtendingsystem.

The implementation of subtending is described in these sections:
• “Star Management” on page 89
• “Daisy Chain Management” on page 93
Each section provides both the features of and the limitations for implementing each subtendingapproach. You can also combine the star and daisy chain approaches to effectively implementsubtending.
Star Management
In a star configuration, you can attach up to three systems (subtended systems) directly to theone system that connects on the edge of the network (subtending system). The subtendingsystem aggregates the traffic from the subtended systems, switches all the traffic (its own andthat of the subtended systems), and provides the network uplink. Features of this managementapproach include:
• shorter segment costs rather than the longer length cost of a daisy chain
• more cost effective than running fiber optic cable to new areas or to areas with a smallnumber of subscribers
Each system, whether subtending or subtended, can connect to and manage subscriber traffic(modems).
“Star Physical Implementation” on page 89 shows how to set up a star configuration usingAvidia systems. “Star Configuration” on page 92 shows how to configure the system toimplement the appropriate connections.
Star Physical Implementation
The relationship of subtending in a star configuration is shown in the following figure.The example shows an OC3 interface as the network uplink for the entire subtended system. AnAV8000 or AV3000 is the subtending system. Three chassis are subtended and are at threeseparate physical locations (sites). The subtending connection is through a DS1 link.
It is important to note that you cannot use the same card to subtend and besubtended. For example, a DS1 card has eight ports; you cannot use one portto subtend another port on the same card.
Subtending Multiple Systems
90 AV8000 Installation Manual
The following sections describe how to select cards for the various subtending connections. Thefigures use the sample system shown above as an example.
Select the uplink card. Install one card for thenetwork uplink, such as the ATM switch shown tothe right, in the subtending system. The card mustreside in slot 11 or 12 for an AV8000 or slot 2 for anAV3000. Select either a DS3, an OC3, or aDS1/DSX-1 for an AV3000 or AV8000 system.
Select a card that accommodates the requirednetwork uplink bandwidth for all the systems that areaggregated by the subtending system. Ensure thesubtending system’s network uplink card is not abottleneck for traffic. For example, use an OC3 orDS3 card for larger systems since these cardsprovide greater bandwidth. Use a DS1/DSX-1 card for an initial implementation where Avidiasystems have only a few cards with the intention of expanding service in the future.

Daisy Chain Management
A daisy chain is a serial link (or cascaded link) of up to three systems that has one networkuplink connection and is viewed as one integrated system. A daisy chain is an approach formanaging systems to support subscribers who are physically separated by distance. The daisychain comprises:
• one system functioning on the edge of the network to aggregate and switch ATMtransmissions and provide the network uplink
• up to two systems functioning as access devices
Each system, whether subtending or subtended, can connect to and manage subscriber traffic(modems).
“Daisy Chain Physical Implementation” on page 93 shows how to set up the daisy chain usingAvidia systems. “Daisy Chain Configuration” on page 95, shows how to configure the systemto implement the appropriate connections.
Daisy Chain Physical Implementation
The relationship of subtending in a daisy chain configuration is shown in the following figure.Use two cards per system to connect a daisy chain. One card, used as a network-side interface,connects to the next system upstream in the chain. Upstream connects toward the networkinterface. The second card, used as a subscriber-side interface, connects to the next systemdownstream in the chain.
The example shows an OC3 interface as the network uplink for the entire subtended system. AnAV8000 or AV3000 is the subtending system. The two chassis are subtended and are at twoseparate physical locations (sites). The subtending connection is through a DS3 link.

AV8100 SYSTEM SPECIFICATIONS
The AV8100 voice shelf fits into a standard 23-inch Telco rack and comprises two parts:
• voice shelf chassis with:
– 20 card slots
– protection ground
– interfaces for ADSL data in, POTS, and ADSL data stream out
• up to 20 ADSL POTS splitter cards
The POTS splitter card, in the AV8100 voice, combines the incoming ADSL data from theAV8000 integrated access concentrator with the analog voice signal (POTS) from a voiceswitch. This multiplexed ADSL data stream is sent to the subscriber.
From the subscriber, the POTS splitter card receives multiplexed ADSL data from thesubscriber. This data stream is split into two signals: ADSL digital data and POTS voice signals.The POTS splitter card sends the voice signal to the voice switch and the ADSL data to theAV8000 integrated access concentrator.
ADSL VOICE SHELF SPECIFICATIONS
The AV8100 voice shelf mounts in a 23-inch, 7-foot Telco rack. You can install up to sevenPOTS splitter shelves in a Telco rack. Allow adequate space for cabling.

AV8000 Installation Manual 151
AVIDIA NETWORK CARDS
Network cards provide an uplink interface to an ATM network. They supply both ATM trafficmanagement and physical layer functionality. Only one network card is required to provide alink between the subscriber and the ATM backbone, but you can install a second network cardfor redundancy or for dual homing. See “Redundancy” on page 77 for more information aboutredundancy and dual homing configurations. Network cards are typically placed in networkcard slots 11 and 12; however, 8xDS1 and 8xE1 cards must be placed in subscriber card slots2-10 or 13-21.
Network cards can also provide a subscriber-side connection when used for subtending.Subscriber-side means that the cards do not provide an uplink network connection, but providea connection downstream to another Avidia chassis that is being subtended. See “SubtendingMultiple Systems” on page 86 for more information about how to select and place networkcards for this application. For this type of application, the OC3 card can be placed in subscribercard slots 2-10 or 13-21

OC3 Network Card
The OC3 network card provides uplink transmission at a rate of 155.52 Mbps and providesconnection to the ATM backbone network as a SONET-based fiber-optic User NetworkInterface (UNI). It has two physical (dual-PHY) SONET interfaces, each with a transmit andreceive port. Under normal operation, all traffic is carried through the first interface; the secondis not used. For Automatic Protection Switching (APS), use the second interface to providebackup to the first.
Three versions of the OC3 network card are available:
• The AV311 OC3 network card provides a multi-mode, long-haul SONET connection.
• The AV312 OC3 network card provides a single-mode, intermediate-range SONETconnection.
• The AV313 OC3 network card provides a single-mode, long-range SONET connection.
Cabling
With an AV311 OC3 network card, use multimode fiber with SC fiber connectors. With anAV312 OC3 intermediate-range (IR) network card or an AV313 OC3 long-range (LR) networkcard, use single mode fiber with SC fiber connectors. Select an appropriate fiber-optic cable toconnect to your OC3 network card by using the following table.
For information about running loopback tests on this network card, see the Avidia SystemConfiguration and Management manual.

In addition to the status LEDs, the front panel displays the following components:
• T1 PORT SELECT pushbutton, when pressed, selects a port (1 through 8). Selection of anyport performs two functions: lights the corresponding LED and activates the associatedBantam test jacks. When a port is deselected (no port), the port LED does not light, and theBantam test jacks remain inactive.
• Bantam test jacks provide monitoring and direct access to the transmit and receive paths foreach T1 port (each with Tip and Ring signals):
– The Equipment IN and OUT jacks provide direct access to the transmit and receivesignals of the active T1 port. The Equipment OUT jack supplies the transmitted outputsignal from the active T1 port; the Equipment IN jack feeds the received input to theactive T1 port. A jumper cable connected between Equipment IN and OUT jacksprovides loopback to test the card functionality and to isolate malfunctions of the T1card for the active port.
– The Line IN and OUT jacks provide direct access to the transmit and receive linesignals from the active remote port. The Line OUT jack monitors the transmitted linesignal from the active remote T1 network interface port; the Line IN jack monitors thereceived line signal to the remote T1 network interface port. A jumper cable connectedbetween Line IN and OUT jacks bypasses the T1 card, allowing isolation of amalfunction of the network line function for the active port
– The Equipment MON and Line MON jacks provide high impedance test points to beused for monitoring (example, T1 test equipment). The Equipment MON jack providesaccess to the T1 output. The Line MON jack provides access to the external line.

– The Equipment IN and OUT jacks provide direct access to the transmit and receivesignals for the active DSX-1 port. The Equipment OUT jack supplies the transmittedoutput signal from the active DSX-1 port; the Equipment IN jack feeds the receivedinput to the active DSX-1 port. A jumper cable connected between Equipment IN andOUT jacks provides a loopback test to isolate a malfunction of the DSX-1 card for theactive port.
– The Line IN and OUT jacks provide direct access to the transmit and receive signalsrelating to the remote end. The Line OUT jack monitors the transmitted line signalfrom the active remote source; the Line IN jack supplies the received line signal to thatremote unit. A jumper cable connected between Line IN and Line OUT jacks bypassesthe DSX-1 card, allowing isolation of a malfunction of the network line function forthe active port.
– The Equipment MON and Line MON jacks provide high impedance test points to beused for monitoring (example, test equipment). The Equipment MON jack providesaccess to the output of the DSX-1 card; the Line MON jack provides access to theexternal line.
For information about running loopback tests on this card, see the Avidia System Configurationand Management manual.

AVIDIA SUBSCRIBER CARDS
Avidia subscriber cards provide two-way data communication with the subscribers.Subscriber cards are currently available in several transmission technologies: ADSL,cell SDSL, frame SDSL, and IDSL. You must select subscriber cards for the AV8000 that arecompatible with the subscriber-end equipment:
• Select cell DMT ADSL subscriber cards to connect to cell-based DMT ADSL modems.
• Select frame SDSL subscriber cards to connect to frame SDSL modems.
Cell subscriber cards operate with a data stream of fixed length. The advantage of this format isthat the network does not have to handle different sizes of packets or frames. This broadbandtechnology transmits data quickly and efficiently. There are three cell subscriber cards: AV541,AV541-LP, and AV522.
Frame-based cards operate with a data stream of variable length. By using only a few bytes ofoverhead, the frame format makes efficient use of each frame. This means that more of theframe bandwidth is used for sending user data and less for overhead. Two Avidia cards areavailable for frame-based data: AV421 and AV412.
The table below lists all the subscriber cards available for the AV8000 system.

Management Ethernet
Chassis backplane
Provides an RJ-45 Ethernet port for remote management. The interface provides 10/100BASE-T Ethernet service. Through the connector labeled MGMT. 10/100BASE-T, you can use the Command-Line Interface with Telnet, Web-Based Interface software, or StarGazer software for system configuration and management.The other connector is reserved for future use.
Subscriber Interface
Subscriber xDSL(S2 through S10 and S13 through S21)
Chassis backplane
Provides 18 backplane connections for subscriber lines to interface to subscriber cards. The connection is made using 25-pair champ connectors labeled S2 through S10 and S13 through S21. Connectors support all xDSL subscriber transmission, with up to 24 subscribers interfacing to one subscriber card through the champ connector (one subscriber card equates to one chassis slot). The backplane supports up to 432 xDSL ports.Also, provides a backplane connection for an 8xDS1 or an 8xE1 network card that can be placed only in a subscriber card slot (limited by backplane connector).
Network Interface
DS3 Chassis backplane
Provides two DS3 interfaces between the AV8000 and the ATM backbone network. For each network card interface, one BNC connector is used to transmit, and the other connector is used to receive over coaxial cable. Each set of interface connectors is shared between network card slot 11 and network card slot 12. The DS3 card provides one primary port and one redundant DS3 port per card. Only one DS3 port can be active on the card at a time. The DS3 cards in slots 11 and 12 can be configured in redundant mode, where a failure on one card causes switchover to the other card.
10/100BASE-T Chassis backplane
Provides 10/100BASE-T interface between the AV8000 and a frame-based Ethernet WAN backbone network using RJ-45 connectors. Two interfaces are provided for each of the two network card slots. Each interface has one RJ-45 jack. The 10/100BASE-T connectors are reserved for future use.
Appendix A: System Specifications

8xDSX-1 Network Card Chassis backplane(SL11 and SL12)
Provides a short-haul DSX-1 connection for interface to 8xDSX-1 network cards installed in slots 11 and 12. The connection is made using 25-pair champ connectors, SL11 and SL12. One connector is for the transmit (Tx) signal for both network card slots; the other connector is for the receive (Rx) signal for both network card slots. Use both the SL11 and SL12 champ connectors for transmit and receive for the network cards in slots 11 and 12.
8xDS1 Chassis backplane(Slots S2 through S10 and S13 through S21)
Provides a long-haul DS1 connection for interface to 8xDS1 network cards. The connection is made by using 25-pair champ connectors labeled S2 through S10 and S13 through S21. This network card functions in any subscriber card slot (slots 2 through 10, and 13 through 21).
8xE1 Chassis backplane(Slots S2 through S10 and S13 through S21)
Provides a long-haul E1 connection for interface to 8xE1 network cards. The connection is made by using 25-pair champ connectors labeled S2 through S10 and S13 through S21. This network card functions in any subscriber card slot (slots 2 through 10, and 13 through 21).
OC3(not shown in figure)
OC3 network card front
Provides a dual-PHY SONET interface between the AV8000 system and the ATM backbone network. Dependent on which OC3 network card you selected, the connection is made using either an SC single mode fiber connector or an SC multimode fiber connector that is located on the front of the OC3 network card. The primary SC interface is for the primary fiber-optic line; the secondary SC connector is for the secondary (redundant) fiber-optic line. If the OC3 is the sole network card in the AV8000, it must be installed in slot 12. In a subtended system or when using either load sharing or redundant network cards, a second network card is installed in slot 11. Added line or subtending OC3 cards can also be installed in any subscriber card slot.

PVC Permanent Virtual Circuit is a logical connection comprising a predefined static route across a packet-switched network that is always in place and always available. The end-points in a PVC circuit are pre-defined and fixed by the network manager.
PVCC Permanent Virtual Channel Connection. A Virtual Channel Connection (VCC) is an ATM connection in which switching is performed on VPI/VCI fields of each ATM cell. A PVCC connection is normally provisioned by some network management function and left in place indefinitely.
PVPC Permanent Virtual Path Connection. A virtual Path Connection (VPC) is an ATM connection in which switching is performed on only the VPI field of the ATM cell. A PVPC connection is normally provisioned by some network management function and left in place indefinitely.
Q
QAM Quadrature Amplified Modulation. A two-dimensional modulation scheme used for ADSL. CAP is a special case of QAM. In QAM, a single carrier frequency is modulated in both sine and cosine components.
QoS Quality of Service. QoS is an equal function of both transmission performance and service availability. Term for a set of categories and their parameter values which determine the overall performance of a given virtual circuit. These configured traffic parameters are assigned to a specific virtual circuit and specify how swiftly and how accurately data is transferred from the sender to the receiver. The ATM Forum has defined QoS parameters that define various levels of performance for the User Network Interface (UNI).
QoS categories There are five basic service categories supported by ATM traffic management: Constant Bit Rate (CBTR), Real-Time Variable Bit Rate (rt-VBR), Non-Real-Time Variable Bit Rate (nrt-VBR), Available Bit Rate (ABR), and Unspecified Bit Rate (UBR). Each of these categories service clearly defined applications, and have their own data types, and QoS parameters.
QoS service parameters
A set of parameters that characterize the performance of an ATM connection. These include: Peak-to-peak Cell delay Variation (p-pCDV), Maximum cell transfer delay (max CTD), Cell Loss Ratio (CLR)
Appendix D: Glossary
AV8000 Installation Manual 219
QoS traffic parameters A set of parameters that describe the traffic characteristics of the source and the connection. These include: Peak Cell Rate (PCR), Cell delay Variation Tolerance (CDVT), Sustainable Cell Rate (SCR), Maximum Burst Size (MBS), and Minimum Cell Rate (expected) (MCR).
R
RADSL Rate Adaptive DSL. An extension of DSL which encompasses a wide variety of data rates. These rates are dependent upon the condition of a given transmission line and its signal capabilities.
rate adaptation A system that is rate adaptive is capable of assessing the conditions of the line (local loop), determining the maximum allowable bit rate that can be implemented, and then configuring the transmission to realize the maximum bit rate possible under the present conditions. Rate Adaptation is a feature of DMT used with ADSL.

222 AV8000 Installation Manual
SVC Switched Virtual Circuit. A virtual circuit connection which is established across a network on an as-needed basis. This circuit exists only for the duration of the data transfer, and then it is destroyed. The user defines the end-points when the call is initiated—the connection is broken at the termination of the call. Unlike a PVC, the end-points of the communication are not established and fixed by the network manager but by the call itself.
subscriber A subscriber is usually an individual end-user or group of individual end-users of a telecommunications service or equipment provided by a service provider (phone company, ISP, ASP).
SVCC Switched Virtual Channel Connection. A switched VCC circuit is one which is created and then destroyed, dynamically, through control signaling. LIke a PVCC connection, the ATM connection is performed using both the VPI and VCI fields of the AYTM cell.
switch A switch is a system or device which interconnects circuit paths by opening certain connections and closing others in order to create a temporary path from a specific source device to a designated destination device.
